TLDR
In this paper, the water transport numbers for protons in a variety of available poly (perfluorosulfonic acid) membranes are presented as a function of water content, and it is shown that, for membranes equilibrated with water vapor over a wide range of activities, a water drag coefficient of unity is observed.About:

Polymer Electrolyte Fuel Cell Model
TL;DR: In this paper, an isothermal, one-dimensional, steady-state model for a complete polymer electrolyte fuel cell (PEFC) with a 117 Nation | membrane is presented, which predicts an increase in membrane resistance with increased current density and demonstrates the great advantage of a thinner membrane in alleviating this resistance problem.
